New WACR Radar Data Available for AWARE Campaign
Nov 16, 2016       
The W-band ARM Cloud Radar-Active Remotely-Sensed Cloud Locations (WACR-ARSCL) provides cloud boundaries and best-estimate time-height fields of radar moments. WACR observations are corrected for velocity aliasing, and then significant detection masks are produced. The corrected WACR measurements are combined with observations from the micropulse lidar, ceilometer, soundings, rain gauge, and microwave radiometer, low-level clutter is [...]

New Scanning ARM Cloud Radar – Advanced – Velocity Azimuth Display (SACR-ADV-VAD) Product Released to Evaluation
Nov 16, 2016       
The Scanning ARM Cloud Radar-Advanced-Velocity Azimuth Display (SACR-ADV-VAD) value-added product (VAP) provides profiles of horizontal wind estimates at cloud level, using observations from the Hemispherical Sky Range Height Indicator (HS-RHI) scan strategy of the Ka-Band Scanning ARM Cloud Radar (KASACR). The VAD technique was historically used to retrieve wind field properties using weather radars. SACR-ADV-VAD employs [...]

Alpha 1 of ARM’s New Modeling Effort Now Released
Jul 31, 2016       
In May 2015, the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility began a pilot project to design a routine, high-resolution modeling capability to complement ARM’s extensive suite of measurements at the Southern Great Plains megasite. This large-eddy simulation (LES) modeling capability has been named LASSO—the LES ARM Symbiotic Simulation and Observation [...]

New Version of Interpolated Sounding VAP Released
May 09, 2016       
A new version of the Interpolated Sounding (INTERPOLATEDSONDE) value-added product (VAP) is released for use with historical data and current production. The INTERPOLATEDSONDE VAP transforms sounding data into continuous daily files on a fixed time-height grid at one-minute time resolution from the surface up to a limit of approximately 40 kilometers. The grid extends to [...]
